Abstract — Stroke-Associated Pneumonia (SAP) is one of the most critical and life-threatening complications following acute stroke, significantly worsening patient prognosis and increasing mortality rates. This paper presents a machine learning-based Clinical Decision Support System (CDSS) designed to predict lung condition risk in stroke patients admitted to intensive care and general wards. The system employs a comprehensive preprocessing pipeline encompassing missing value imputation, feature normalization, and class balancing using SMOTE to address real-world clinical data challenges. Four supervised learning algorithms — Logistic Regression, Random Forest, XGBoost, and a Deep Neural Network — were systematically compared using stratified 5-fold cross-validation. Random Forest achieved the best performance with 92% accuracy and 0.97 AUC on the test set. SHAP (SHapley Additive exPlanations) analysis was applied to provide clinical interpretability, identifying key predictive features including dysphagia severity, GCS score, age, and mechanical ventilation status. A web-based dashboard enables real-time risk prediction and clinical decision support at the point of care, facilitating timely preventive interventions for high-risk patients.
